Abstract
A sensor element () measures a Hall voltage generated by a movable magnet (). For this purpose, the sensor element () comprises a ceramic base element () which has connected therewith a detector element (). The detector element () is protected with the aid of a cover element () against an aggressive environment produced by fuel or fuel vapors in a fuel tank () of a motor vehicle. The detector element () has connected therewith electric conductors () which are routed through the cover element () and/or the base element () for connecting the detector element () with a voltage source and/or an evaluation unit. The cover element () and possibly the base element () reliably encapsulate the detector element () against the aggressive environment such that by simple constructive measures the service life of the sensor element () is increased.
